结合“到”故事板中 [英] Binding to 'To' In Storyboard

问题描述

我会尽力使这个，我可以这么简单。

I'll try to make this as simple as I can.

我想这样做：

<Storyboard x:Name="MoveToLocation">
   <DoubleAnimation Duration="0:0:0.5" To="{Binding X}" Storyboard.TargetProperty="(UIElement.RenderTransform).(CompositeTransform.TranslateX)" Storyboard.TargetName="grid" d:IsOptimized="True"/>
</Storyboard>

正如您可能已经注意到了绑定到属性不起作用。它似乎只接受静态值。

As you may have noticed the Binding on 'To' Property does not work. It seems to only accept static values.

怎样才能做到这一点的动画与MVVM？我不能只是把静态数据，因为它是不会改变。

How does one do this animation with MVVM? I cant just put in static data, cause it's going to change.

感谢。

推荐答案

DoubleAnimation是也不是一个 FrameworkElement的因此，绑定不工作，要么。看到我的回答你的previous <一个href=\"http://stackoverflow.com/questions/2984788/silverlight-binding-to-translatex\">question.

DoubleAnimation is also not a FrameworkElement hence binding doesn't work to that either. See my answer to your previous question.

为了在这里实现你的目标，你将需要采取你的的DataTemplate 的内容并把它变成一个用户控件。然后，这个新的控制可以公开一组的依赖属性，你需要绑定到，其中包括一个来的故事板值。

In order to achieve your goal here you will need to take the contents of your DataTemplate and turn it into a UserControl. This new control can then expose a set of dependency properties that you need to bind to, including one for To value of the storyboard.
